BUILDING coNsTnUoi'rIonQ Application filed July 14, 192s. are n stiest The leading object of the present inven- I tion is to provide a simple, efficient and comparatively inexpensive way of forming a ceiling, wall, partition and the like of 'plas- I I II II Ichps will, now be described. 17 designate t er-board, slabs'or equivalent material, with out employing metallath or the like, as now commonly practiced, for supporting the plastering material. -A further object resides'in the provision of specially formed slabs and clips for accomplishing the results sought by said leading object.

A further object is to provide an archform shaped to preventlateral movement of the clips employed.

The invention consists of the improvements hereinafter described claimed.

The nature, characteristic features and scope of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof and in which I Fig. 1, is a fragmentary. view, in section, of a ceiling formed in accordance with th present invent-ion. I

Fig. 2, is a top or plan view thereof,

Fig. 3, is a plan view of one of the slabs, Fig. 4, is a side view of one of the clips, and i 3 Fig. 5, is a side view of an arch-support.

For illustrative purposes I have shown in the drawings an embodiment of the present invention as'applied to ceilings and the following description is restricted thereto, .although obviously the invention is applicable to walls, partitions and the like, and further, general details of construction and arrange ment of parts may be varied without depart- I and I finally ing from thespirit or scope of the'present II I I I I forms-and betweenthe bevels of'the slabs.

invention.

In the drawings 10, designates a slab of suitable material. This may be plasterboard or a cork, saw-dust or equivalent composition, the ingredients of which form no part of the present invention. The 'edgesof said slab are beveledas at 12, for a'purpose' Opposite sides of the to presently appear. slab 10, are provided with a plurality of slots 13, usually in the form of saw-kerfs as this forms a ready and inexpensive manner tally arranged =myslabs and clips.

of formation. These. slots ver-.0 accommo date spring clipsv about to' be'described. "The clips areof metal, formed in one piece and each comprises a substantially'looped part the ends of which are extended inwardly 1n parallelism, as at 15- 15, to provide legs and then are extended outwardly with respect to parts 15 15 to provide opp sed feet 16. 'The manner'of using such slabsand I-beains as, are used inceilingconstruction" and between adjacent "I-bea'ms are horizon- I I I Temporary supports or frames 18 are employed "as usual" in this"- class of 5 Work.

Upon these supports and between the lLbeams :1 position my slabs/1O as shown 1111' Fig. 1. I next position upon'each'slab 10 an arch-form 19.-opposed sides of which are flanged at 20. Each flange is slot-ted. inregister with "the slots 13 of a slab 10. 'Each slotted portionof a flange 20 is pro 'vided with a lip 22, capable of being bent from the position shown in Fig. 5,'to that shown in Fig. 2, in or'der to provide a guard as hereinafter described. With the arch? forms superimposed upon the slabs I next fit to the registering slots of the arch-forms and slabs the clips above described- In the connection it is to be noted that the lips 22 of the arch-forms are in open position as shown in Fig. 5; The parts 1515 of the with the feet 16 beneath the slabs and the clips ar'e accommodated in said slotted partslooped parts 1i projected above the archforms asclearly shown in Fig. 1. Each loop part, acts as aspring to normally spread aparta pair of legs 15. Thev lips 22 ar'ethen bent downwardly to close the open ends of the slotsyof the arch-forms thus preventing I lateral or side-wise movement of theclips.

This is important whileithe'mechanicsxare I at work and before plaster is applied. I

A fillof plaster or the like 23, is then ap plied between the I-beamsQupon thearch- Airspaoes 24 are thus left between the slab I tops and thearch-forms I inforcing rods are usually employed. When the material 23 has set the temporary Conventional rehand side of Fig. 1. Since a slabis in effect a rough-coat of plaster but very thin coatv of finishing plasteris necessary. In the event that it becomes necessary to cut away a portion of a slab for any reason, as in installing light fixtures for instance, said clips serve to maintain the remaining por tlon of the sin-bin position. The clips also function to preclude sidewisc movement of y the arch fo'rms.

The beveled parts of adjacent slabs serve as a good anchorage for the plaster or like v s y y air space between'a slab and an arch-form.

2. In combination, I-beams, slabs the "opposed sides of Which are slotted, positioned between said I-beams, an arch-form mounted upon each slab andfhaving flanged parts slotted, in register wi'thsaid slab slots, each slotted portion of said arch-form being provided with a lip for closing aslot opening to prevent lateral movement of a clip, clips having looped tops and parallel leg portions terminating in opposed feet fitted within said registering slots with the feet arranged beneath the slabs and th'elooped tops above said ZLICllrfOIIIlS and a plaster or like fill between said beams and upon said archforms, there being thus left an air space between a slab and an arch-form.

In combination, I-beams, slabs the opposed sides of which are slotted, positioned between said I-beams, an arch-form mounted upon each slab and having flanged parts slotted in register with said slab slots, clips having loopedtops and parallel leg portions terminating in opposed feet fitted within said registering slots with the feet arranged beneath the slabs and the looped tops above said arch-forms, a plaster or like fill between said beams and upon said arch-forms, there being thus left an air space between a slab and an archform, and a thin finishing coat of plaster for the exposed face of the slabs.
